# Tar-zxvf./eaccelerator-0.9.5-beta2.tar.bz2 # Cd eaccelerator-0.9.5-beta2 # Export PHP_PREFIX = "/usr/local" (import the PHP installation directory to the environment variable. the default value of FreeBSD is/usr/local) # $ PHP_PREFIX/bin/phpize #./Configure -- enable-eaccelerator = shared -- with-php-config = $ PHP_PREFIX/bin/php-config # Make # Make install 4. after The INI file is configured and installed, configure the php. ini file. the eAccelerator provides two configuration and call methods. Install in Zend extension mode: # Mkdir/tmp/eaccelerator # Chmod 777/tmp/eaccelerator 5. verify the installation result and access your phpinfo () page through a browser or run php-I to get the php configuration information. if the following information is displayed, the installation is successful. This program makes use of the Zend Scripting Language Engine: Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies with eAccelerator v0.9.5-beta2, Copyright (c) 2004-2006 eAccelerator, by eAccelerator Zend Optimizer3.0.1 is also installed on my machine, so the following information is displayed: This program makes use of the Zend Scripting Language Engine: Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies with eAccelerator v0.9.5-beta2, Copyright (c) 2004-2006 eAccelerator, by eAccelerator with Zend Extension Manager v1.0.10, Copyright (c) 2003-2006, by Zend Technologies with Zend Optimizer v3.0.1, Copyright (c) 1998-2006, by Zend Technologies if you enable the debug option of eAccelerator, you can see information similar to the following in the log: Eaccelerator_lock ("count "); Eaccelerator_put ("count", eaccelerator_get ("count") + 1 )); ?> Eaccelerator_unlock ($ key) releases a lock based on $ key Eaccelerator_cache_output ($ key, $ eval_code, $ ttl = 0) caches $ eval_code output $ ttl seconds. (the $ ttl parameter is the same as eacclerator_put parameter.) example: Eaccelerator_cache_result ($ key, $ eval_code, $ ttl = 0) caches $ ttl seconds for the execution result of $ eval_code code (the $ ttl parameter is the same as eacclerator_put parameter). For example: Eaccelerator_cache_page ($ key, $ ttl = 0) caches the entire page for $ ttl seconds. For example: Eaccelerator_cache_page ($ _ SERVER ['php _ SELF '].'? GET = '. serialize ($ _ GET), 30 ); Echo time (); Phpinfo (); ?> Eaccelerator_rm_page ($ key) deletes the cache executed by eaccelerator_cache_page (). the parameter is also $ key. 2. the powerful power of eAccelerator in php code accelerated by using eAccelerator: (The code may not work in cli mode) Class test_cache { Var $ pro = 'hello '; Function test_cache (){ Echo "Object Created! \ N "; } Function func (){ Echo ', the world! '; } Function now ($ t ){ Echo date ('Y-m-d H: I: S', $ t ); } } $ Tt = eaccelerator_get ("test_tt "); If (! $ Tt) { $ Tt = new test_cache; Eaccelerator_put ("test_tt", $ tt ); Echo "no cached! \ N "; } Else { Echo "cached \ N "; } Echo $ tt-> pro; $ Tt-> func (); $ Tt-> now (time () + 86400 ); ?> In addition, it is said that eAccelerator support has been integrated in the famous vBulletin 3.60Beta version.
